# deploy.sh - A script to install the trmm-lam binary on a Linux system
# Optionally, you can provide arguments to run the installer immediately after download like:
# # ./deploy.sh -u <api-url> -a <api-key> -c <client-id> -s <site-id>
#
# Bad practice, but you could also pipe this script to bash like:
# # curl -sSL https://raw.githubusercontent.com/soarinferret/trmm-lam/main/deploy.sh | bash -s -- -u <api-url> -a <api-key> -c <client-id> -s <site-id>
